BUTTON-SEWING MACHINE."

Specification of Letters Patent.

Patented Nov. 30, 1915..

Application filed January 7, 1914. Serial No. 810,894.

' To all whom it may concern Be it known that I, JOSEPH E. GADBOIS, a citizen of the United States of America, and resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Button-Sewing Machines, of which the following is a full, clear, and exact defeeder, a finder or device for engagement .tory needle bar. z ation of the machine is such that the button in the diametrically opposite eyes of the button which is operative to rotatively move the button so that the opposite eyes thereof will be in a line longitudinally of the machine, that is one extending from the front to the rear actuating mechanism operating the feed slide to transfer the eye positioned button forwardly into the presser foot which is constructed for the reception-and retention thereof; an organization of the sewing machine whereby the presser foot (capable of a rising and lowering motion for clamping and disengaging the fabric) together with the throat plate are reciprocated within a short range of movement in the longitudinal line of the machine so that the button is successively shifted during the sewing operation to bring the opposite eyes thereof alternately coincident with the axial line of the needle carried by the vertically reciproca- Furthermore, the organifinder, and button transferring -devices have their operations in their own time, while the sewing mechanism is idle, and vice versa, the driving mechanisms for the devices operative on the button and the button sewing mechanism having means for-their control which are highly important in contributing to the successful automatic action of the machine; and the machine, moreover, includes an automatically operative device for severing the threads between the needle and shuttle, beneath the fabric, and below'the throat plate so that after the button has been sewed onto the fabric and coincident with the starting of the mechanism which feeds the next button into the presser foot, the

fabric with the button sewed thereon may be withdrawn from its position between the throat plate and presser foot, without drawing out any of the needle thread and shuttle thread therewith. i

The invention is described in conjunction wlth the'accompanying drawings and is set forth in the claims.

In the drawings :-Figure 1 is a plan view of the machine shown as of duplex character, that is having mechanisms-for the sew- 1ng onto the fabric of two buttons simultaneously. Fig. 2 is a. side elevation of the machine; Fig. 2? is a detail plan view showing the separable character of the button receiving presser foot. Fig. 3 is a longitudinal vertical sectional view on line 3-3, Fig.

1. Fig. 4 is a partial longitudinal vertical sectional view on line l-'l, Fig. 1. Fig. 5 1s a vertical cross sectional view on line 55, Fig. 3, as seen looking in the direction of the arrow. Fig. 6 is a partial vertical sectional view on a plane transversely of the machine 4 as taken on line 6-6, Fig. 3,the sameparticularly showing the button-hole. finder. Fig. 7 is a view longitudinally of the machine and at right angles to Fig. 6', showing the finder ashaving engaged and positioned the button with its opposite eyes alined with the presser foot. Fig. 8 is a view similar to Fig. 7, but showing the finder as having been retired downwardly and the button as having been fed forwardly into the presser foot. Fig. 9 is an inverted plan view of the machine. Fig. 10 is a perspective view showing constructions for interengagements between the pulleys employed for actuating thesewing mechanism and the button positioning and feeding. Fig. 11 is, a side view to show the adjustable capability of the crank pin which longitudinally shifts the presser foot and throat plate.

For brevity and the avoidance of con fusion, the description will be mostly con fined to an organization comprising a single button-controlling mechanism and a single hutton-sewing-on mechanism, and the thread severing device therefor.

In the drawings, A represents the-table of the machine, B representing one of the goose-neck standards thereon.

C represents the throat plate, I) the needle bar, carrying the vertical needle a as usual to which the needle thread in is supplied as usual, and E represents therotary shuttle, the sewing mechanism including the needle,"

and shuttle, which I have employed, being of the Singer type.

F represents the presser foot which is capable of being lifted and lowered to disand forth reciprocation of the presser foot and throat plate in unison; while the pulley H on the shaft H actuates the shaft J having cams and other appliances thereon which actuate the button-finden'and buttonfeeding or transferring device and controls the belt shifter K fer the belt L which alter nately drives the pulleys G and H; and one of which cams on such cam shaft J automatically causes the stopping of the machine after a button has been sewed onto the fabric. The shaft H when driven by the belt and pulley, drives the cam shaft J through the spiral gear wheels H and H, the horizontal shaft H, the pinion H on the shaft H and the gear wheel J 2 on the cam shaft. I

'The sewing machine shaft B is driven from the sleeve shaft by means of spiral gears G G, seen in Fig. 4, the latter gear G being on a horizontal shaft G which QX- tends to within the goose-neck standard B and has connection by bevel gear wheels Cr and G with a vertical shaft G which shaft through the bevel gear wheels G and G has connection with the shaft 13 which operates the needle bar D, and the thread takeup in the usual manner; and the said vertical shaft G through-the bevel gears G and G, drives the shuttle shaft E The buttons are loaded into the oblique 'chute c and by gravity settle in the receiver I) provided therefor and formed as a short horizontal continuation of the chutes slightly above the level of the table A. Co-

acting with the receiver is the finder, here shown as consisting of a disk 6 having a pairvof upstanding diametrically opposite small pins 6 spaced corresponding to the separation of the eye holes of the button, and an axially rotative vertical shaft 6 on the upper end of which the finder is carried. The finder also has combined therewith a yoke of light construction, into which the button coming from'the chute into the button receiver Z) is temporarily pocketed or trapped, to be held against any such dis placement in a line foreand aft of the machine as would prevent-the proper registration and engagement of the finder pin in the buttonholes. ,This yoke represented by f, in

' practice is made of a rectangular sheet metal blank having the opposite extremities thereof bent upwardly at right angles to the base portion which is engaged, under the head of the finder, with the carrying shaft 6 K represents the transferring slide behind the button receiver and finder andin the line of the presser foot which is made of such channeled or apertured construction as to permit the reception and engagement of the button when the latter is forwardly forced by the slide from the receiver into such presser foot.

The shaft or spindle, carrying thefinder. is mounted and guided for a vertical up and down motion; and it has rotary motion imparted to it, so long as it is permitted to turn, by means of the small driving band (2* which is driven from the pulley e on the shaft J and around the grooved pulley c aflixed on the "ertical shaft 0 At a suitable time in the operation of the machine after the button has been fed to posit'ion in the yoke 7' within the receiver 7/, the revolving finder shaft is permitted to rise under the reaction of its elevating spring until its pins e strike against the bottonrof the button, which button is resisted in an.

upward direction by the inturned ledges or flanges b at the top of the receiver; and then, so soon as the pins engage in the buttonholes, the line intersecting both of which may be in any direction, as the buttons come into the receiver at random, the finder moving still farther upwardly for such engagement, the buttons are rotated just far enough to aline the buttons truly in the fore and aft line of the machine, which, accomplished, the further rotary motion of the upright shaft and the finder is arrested by the engagement of the stop lug e on the upper side of the pulley 6 with a shoulder of a sleeve 9, which surrounds an intermediate part of the shaft 6 and, through which said shaft is freely rotatable; but the said sleeve is non-rotative, but is capable of a slight degree of' vertical movement, it beinghnder the reaction in an upward direction of the spring g and caused to have itslowering movement by the engagement therewith of a bent arm which is carried as an upper end extension of a bar 9 and which bar has a lug or short arm 9 at its low end in position to be engaged by the approximately horizontal lever 72, fulcrumed ath beneath the table, and subjected to the'ci'owding action of the cam i at the lower end of a lever i which lever coactswith the button transfer slide K.

The lever 71 with the cam is ai'fixed on a rockshaft 7?, indicated in Figs. 2, 3, 7', 8 and 9; and the rocking motion of such shaftto impart the swinging motion to the slide I the time when the slide forwardly pushes 'the button into the'presser foot, is accomplished by a thrust rod 2", horizontally slidable, adapted to engage a fixed upstanding arm 11 ofthe rockshaft and to receive its thrust motion by the wiper cam i revolubly carried by the cam shaft J; and after the w per cam has passed around clear from engagement with the thrust rod, the latter is then free to have its quick retracting move ment from the power of the spring 2' having I thereof in alinement with the needle a, .is

retiring to the rightward to withdraw the transfer slide K to its normal position to bring its left hand end to the position shown in Fig. 7.

The formation of the cam end 2' of the lever z' is such that the horizontal lever h is not released for its .maximum upward throw until an instant after the working end -of theslide is carried beyond theline of the feed of the button to the chute so that a button will surely come into the chute before the upwardly spring pressed parts 6 and q may move to the extent of their capabilities.

The driving pulley e for the finder shaft 6 therefore remains locked to the sleeve during the. greater portion of a cycle of the machine; but as will be perceived in Fig. 6, when the lever k and the connections 9, and g? between it and the sleeve permitthe sleeve to move upwardly to its limit under its spring 9 the finder and its shaft will first move upwardly a little less far because its pins will strike against the bottom of a button at non-perforated parts thereof; and

thus there will be a disconnection between the pulley e and its sleeve, as shown in Fig. 6, .to permit the driving band to cause the rotation of the finder shaft pulley for the operation of the finder; but this operation can only continue after the finder plns have engaged in the button for so much of a revolution as is necessary for the alinement of I the button holes because the stop lug e is so positioned with relation to the hne extending between the finder pins that when the latter have been revolved sufficiently to properly position the button, the reengagement between the pulley and the sleeve will take place.

the vertically movable but non-rotative' sleeve g in conjunction with the finder shaft and its pulley e which is adapted for the lnterlocking with the sleeve as described, is that the rotation of the finder shaft while it is descending to carry its pins out of engagement with the properly alined button holes must be absolutely prevented, for should the catch lug of the finder shaft pulley become disengaged from its stop before the finder pins are lowered entirely out of the eyes of the button, the button after having been properly positioned would lbe rotatively displaced from such position thus destroying the --practicability of the device; but as will be perceived on reference especially to the'sectional views, Figs. 6, 7 and 8, the finder shaft is in clutch with the sleeve in both the lowered and spring lifted positions of the latter and is only out of clutch so that the finder can turn during the interval necessary for the pins to enter the button holes 'and to then turn the button around, as great or small a fraction of a revolution as is necessary to bring the button holes to the proper alinement.

It is to be understood that during a considerable time the driving band running around the pulleys on the cam shaft and .on the upright finder shaft willslip on such pulleys.

The presser foot is carried at the extremity ofa return bent fiat spring F the rear portion of which is secured to a horizontal slide P guided within the hollow goose neck whereby, because of the resiliency of such spring the presser foot may have a substantially vertical movement so that it may be alternately raised to the level of, and to be in alinement with, the button receiver and transfer slide K and to be lowered to clamp the fabric between it and the throat plate.

The means controlling the rising and falling movements of the presser foot (seen in Figs. 1, .2 and 9) consist in a vertically guided bar m on the side of the goose neck and to the angularly turned lower extremity m of which the lower portion of the presser foot carrying the spring is connected; the intermediately fulcrunied lever m and the vertical thrust rod m having at its lower end a yoke m which embraces and is subject to the up and down moving action of the cam 11?. on the shaft J.

The aforementioned slide P guided in a slideway P therefor in the goose neck, shown in Fig. 3, and to which. the presser foot carrying spring is connected, has reciprocatory movement for changing the position of the button so that the eyes thereof will be alternately coincident with, the line of movement of the needle imparted thereto by a pitman rod 00. which is connected to the slide and to a crank pin n carried on the face of a gear wheel a mounted in an intermediate part of the goose neck and in mesh with which is a gear wheel a on the sewing machine shaft B The presser foot F, as represented in Fig. 2 is-made with opposite jaws 0 0 pivoted at 0 0 at a thickened or reinforced part of the presser foot carrying spring F these 'jaw's being normally held in approached relations by the spring 0 and the inner edges of these separable jaws are suitably channeled or recessed for the reception therein of a button transferred thereint'o by the feed mechanism.

After the button shall have'been sewed onto the fabric and the sewing thread out, upon the withdrawal of the fabric in a forward direction, the buttons will be dragged out forwardly from within the presser foot; and the making of the opposite portions of the presser foot of yielding mem bers as stated, adapts such presser foot to a the reception and retention therewithin of buttons which may slightly vary as to diameter,

The throat plate C, as indicated in Figs. 3 and 9, has in addition to the forward end portion which is above the table a downwardly offset and rearwardly extended por tion C to which reciprocatory movement in the fore and aft line of the machine in unison with the presser foot is imparted by means of the pitman rod C connected to the crank stud of the wheel n and having connection with the upper end of an intermediately pivoted vertical lever C the pivot being represented by C in Fig. 3, which at its lower end has connection with one end of a transverse horizontal lever C intermediately pivoted under the table, the other end of which is pivoted to the throat plate extension.

-Suitable means for the guidance of the throat plates are provided; and in *Fig. 9 1t is seen that a pair of throat plates for the duplicated machines are formed from a single plate.

Means are provided for the driving of the mechanisms or devices of this machine which are of a somewhat peculiar character, inasmuch as in one complete operation 'of thema'chine betweenthe time it is started and the time it is automatically stopped, the pulley Gr which drives the sewing mechanism is rotated for something like a half or other fraction of the time of the cycle, while the pulley H which actuates the cam shaft J has its rotation during the complete cycle of operation of the machine, that is during the time in which the wheel J 2 and shaft J make, one complete rotation.

M represents a rod horizontally and longitudinally ranging under the table and. formed. with a catch shoulder s on its under side. This rod has a spring 5 applied thereto-for forcing it in a rearward direction,

and at its rear end it has an angular and upturned extension (9 extending into proximity to the forward face of the pulley G and provided with a belt shifter K. Also located beneath the table is a slidable horizontal longitudinal bar or rod Q having a catch shoulder Q having the spring q so applied thereto as to force the bar Q forwardly and provided with a transverse extension g terminating in an upward angular extension 9* in suitable proximity to the rearward face of the pulleyH. I

The pulley G has an internal: face-ratchet surface t indicated in Figs. 4 and 10 of the drawing, with a shoulder 29, and such pillley also has on its outer forward face a stop projection 6 The pulley H- which is made hollow or cup-shaped has therewithin the forwardly spring pressed stud u to be engaged, when the pulley G is rotated, by the belt by the shoulder it? at the end of the ratchet-like surface within the pulley G; and the opposite or rear end of this stud projects outwardly beyond the face of the pulley H.

The shoulder Q of the rod Q is engaged when suchrod is forced against its spring 9 in a rightward direction by a transverse intermediately pivoted spring pressed latch lever R (see Figs. 5 and 9) and the shoulder 8 of the rod M moved forwardly against the spring is engaged by the transverse in- 'termediately pivoted spring pressed latch lever S; and c'oacting with the ends of these levers whlch are opposite their shoulder-engaging portions are cams S and R on the v shaft J.

The rods .Q and M are set in their latched positionsby the starting lever T (see Fig. 9) provided on the under side of the table pivoted at T connected by longitudinal rod- T with. an intermediately pivoted angular lever P all so arranged that a forward swinging of the free end of lever T will cause, through said connections, the forward forcing of rod M and the rearward forcing of rod Q with their extensions.

In the starting of the machine the forward forcingof rod M places the belt on the pulley G, causing the driving of the parts appurtenant to the sewing actions and'at the same time causing the rotation of the pulley H which drives the cam shaft which,

for the most part, pertains to the button feeding. operations. The pulley H is driven from the pulley G by its shoulder 15'' engagmg the inner end' of the spring pressed studu.

' The cam S is so positioned or timed on the cam shaft that after the sewing mechanism has been operated for sewing on the button, it will trip the latch lever S and pen mit the rod M tobe moved rearwardly under the force of-its spring .9 to shift the belt L off from pulley G 'onto pulley H, and

' of such rod M which is just forward of the pulley G rearwardly far enough to be in the path of,'and to intercept, the projection i on the pulley G, causing the positive stoppage of the latter. The belt' now being upon the pulley H causes the running of the latter fcated in suitable proximity v .and 6,0 represents the. pivotally mounted in ,thesame direction-which it had been run ning, 'its spring stud now revolubly clicking past the ratchet shaped surface in the pulley G. This further driving of the cam shaft J by the continued running of the pulley H will be until the shaft J hasmadea complete-revolution, 'whereupon thev cam' R? will trip the latch lever B and liberate the rod Q, which being spring pressed in the forward directionwill bring its extension 9* into the .path of, and to intercept .the outward extension of the stud u andstop the further driving of any of the mechanism of the machine until there is re-starting through the operation ofthe starting lever T. e

The driving belt L when transferred onto the pulley H, and after such pulley has been stoppedlby. the intercepting part 9 will slip on the pulley H until such time as in'the ext starting of the machine it is shifted to run around on and drive the pulley G and the mechanisms actuated thereby. Concurrently with the shifting of the belt from pulley G to pulley H," at the time when the sewing operationhas been completed and the sewing vmechanism remains idle,'the endvwise motion in the rearward direction of.

the rod M is effective for the operation of the shears which sever the sewing thread beneath the, throat plate.

InFig. 9, w represents a fixed shear mem- 3 her located in a horizontal plane under, and.

supportedby, the table" and having in no ,w'ay any connection or coacti'on with the shear member being loto the line of shuttle and the needle;

throat plate, such stitching between the movable lever-like member of the shear,-

\ the arm 10 thereof oppositely from the cutting member and beyond the pivot being pivotallyconnected to a rod or plate M the rearward extension of which latter comprises the belt shifter K.

It is to be explained that while the shaft J makes a complete revolution in one entire operation of the whole machine', the cams thereon which are effective for actuating the button positioning and button transferring devices, areof such form and timing that they are without action on the above named mechanisms'during the time of the sewing of the button through the holes thereof onto the fabric and when the presser foot is low- {ereddown onto the v planeat'which the ea fabric below the level or button is positioned, or ha'sits eyes brought around to thelong1tud1- duplications respond with the number of 'buttons'to be nal alinement, and at .which'time'the transfor of the button into the presser foot is performed; and the cams referred to in' this paragraph in the period after the completion of the button sewing-on action comparatively quickly effect the operation required of them and then pass around out'of engagementv with the devices with whic' they coact duringthe greater part of the cycle of operation.

It will be'noted as may be perceived from the drawings, the gearing connections between the shaft H which drives the mechanism which actuates and controls the button positioning and transferring mechanism, as compared with the gearing which drives the mechanism havingto do with the sewing operations is such that there may be a considerable number of sewing operations as necessary for the proper stitching of the button onto the fabric while the cam shaft J is making but a single rotation.

. As represented in Fig. 11, the crank stud 71. on the-face of the rotary wheel n is made vradially. adjustable whereby the shifting ing, feeding, and sewing machine, are organized'bythe-employment of some prin-- cipal parts in common is apparent from an inspection of the drawings; and in practice the'machine is to be made with as many reof the mechanlsn 'sas will corsimultaneously sewed onto a piece of fabric,
